Deploying an AdvancedHMI Project

[@jesusdiaz839]

of better do you know what are the maximun number of devices to connect?

Hi Jesus, The Modbus/TCP protocol itself has no limit for the number of slaves. The address of the slave is the Ethernet IP address. Serial Communication - Modbus RTU, ASCII According to the Modbus specification, the node range is from 0 - 255, with 0 being the master, 1-247 being the slaves, and 248-255 being reserved addresses. After 32 nodes (1 master + 31 slaves), you may need RS-485 repeaters to ensure proper communications. Regards, Garry

So, the program does generate an exe. Very nice. I am also needing different controls and components then what is offered. Can we make new components with a property screen?

All of Visual Basic is there for you to use. Regards, Garry

Hi Jesus, What method are you connecting the CompactLogix PLCs? Is each of the PLCs assigned a different node number or IP address? Regards, Garry

Copying the .exe shortcut worked great! My problem is that when I run a project via clicking the .exe icon, I am not able to run a second advanced hmi application while working on it on visual studio. I have to close down the first project so I can run the project on visual studio. Any thoughts on this? THANKS!

Hi Imc00rage You should be able to run a second AdvancedHMI as long as the resources are not already being used. If your application is using the Serial port for communication and you try to open this again on the computer it will not work. Usually I will program on a separate computer and transfer the program. Hope this helps you out. Regards, Garry

Thank you for the reply! I will see if I can figure it out. To clarify, I have two AdvancedHMI projects which are reading data from an OPC server. In both, I use OpcDaCom1. One of the projects is finished and it works well. While working on the second project in visual studio, I cannot run it if the first project is opened. Instead, the HMI for the first project pops up. At first I thought it had something to do with the project name, but I will see what I can find. Thanks Garry! Really like the content in your channel
